VideoFormat

Specify video format or name of device configuration file

Description

The VideoFormat property specifies the video
format used by the image acquisition device or the name of a device
configuration file, depending on which you specified when you created
the object using the videoinput function.

Image acquisition devices typically support multiple video formats.
When you create a video input object, you can specify the video format
that you want the device to use. If you do not specify the video format
as an argument, the videoinput function uses the
default format. Use the imaqhwinfo function to
determine which video formats a particular device supports and find
out which format is the default.

As an alternative, you can specify the name of a device configuration
file, also known as a camera file or digitizer configuration format
(DCF) file. Some image acquisition devices use these files to store
device configuration information. The videoinput function
can use this file to determine the video format and other configuration
information.

Use the imaqhwinfo function to determine
if your device supports device configuration files.
